Plasma ionized calcium in hypomagnesaemia.

Ionized calcium

pH-adjusted ionized calcium

Measurement of serum and plasma ionic calcium with the "Space-Stat 20 Ionized Calcium Analyzer".

Ca2+ was measured in sera and plasma from 36 normal subjects (18 men 23-57 years old, and 18 women 20-52 years old) with the Space-Stat 20 Ionized Calcium Analyzer. Within-day and between-day precision (CV) for commercial serum-based specimens varied from 0.64-0.96% and 1.1-3.8%, respectively, depending on their mean concentrations. Plasma and serum showed within-day CV's of 1.05 and 0.79%, res...

Actual ionized calcium (at actual pH) vs adjusted ionized calcium (at pH 7.4) in hemodialyzed patients.

typed double-spaced (including references) with conventional margins. The overall length is limited to five manuscript pages, including not more than one figure or one table. To the Editor: Ionized calcium is now the measurement of choice for evaluating calcium metabolic diseases (1, 2). Ionized calcium may be reported either as the actual ionized calcium, referred to the actual pH of the patie...

Laser ionized preformed plasma

The Facility for Advanced Accelerator and Experimental Tests (FACET) at SLAC installed a 10-TW Ti : sapphire laser system for pre-ionized plasma wakefield acceleration experiments. High energy (500 mJ), short (50 fs) pulses of 800 nm laser light at 1 Hz are used at the FACET experimental area to produce a plasma column. The laser pulses are stretched to 250 fs before injection into a vapor cell...
